Description
Technical field
The utility model belongs to the robotization Non-Destructive Testing of narrow space pipeline and container welding, and technical field is specifically related to a kind of narrow space pipeline and container welding checking tool.
Background technology
Large pressurized vessel in nuclear power station such as steam generator, voltage stabilizer etc., large scale core level pipeline such as trunk line, peace are annotated pipe, fluctuation pipe etc. and are all needed regular Non-Destructive Testing is carried out in its butt-weld before the operation of power station and in operational process, can not occur leaking with the heat eliminating medium that guarantees the High Temperature High Pressure in circuit system.
Because all there is in various degree radiation in the large pressurized vessel of nuclear power station, and size is very large, is to reduce personnel's radioactive doses, improves the efficient that detects, and needs to adopt automation equipment that it is implemented automatically to detect.And the nuclear power station inner space is limited, and has possibly arm, step, elbow isostructuralism obstacle near container, pipe welding seam, causes weld seam both sides that very narrow passage is only arranged, and hinders the enforcement of weld seam self-verifying.Therefore, need a kind of narrow space pipeline of development and container welding checking tool structure badly, thereby the butt-weld that is applicable to used in nuclear power station pressure vessel, large scale pipeline is implemented automatically to detect.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of narrow space pipeline and container welding checking tool are provided, are used for nuclear power station narrow space pipeline and container butt-weld self-verifying.
In order to realize this purpose, the technical scheme that the utility model is taked is:
A kind of narrow space pipeline and container welding checking tool are by forming with lower component: installation base plate, axial stop, circumferential driven unit, circumferential positioning component, probe assembly, axial driven unit, magnet-wheel assembly, scrambler, drive motor;
Installation base plate is the foundation of checking tool, and its two ends connect respectively circumferential driven unit and circumferential positioning component, and intermediate connecting shaft is to driven unit;
Circumferentially driven unit is comprised of magnet-wheel assembly and drive motor, and circumferentially positioning component is comprised of magnet-wheel assembly and scrambler, and the magnet-wheel assembly is used for the band power driven tools along checked container/pipeline outer wall circumferential movement, and testing tool is adsorbed on container/pipeline outer wall; Drive testing tool by drive motor and circumferentially walk, detect by the circumferential position of scrambler to testing tool;
Above installation base plate corresponding connect circumferential driven unit and circumferentially the position of positioning component two axial stop are set, and the gap between the magnet-wheel assembly is across being stuck on circumferential guided way, the instrument that prevents in motion process along checked container/pipeline axial play;
Axially on driven unit, slide block is set, driven unit axially slides up and down vertically, arrange on slide block and implement the probe assembly that weld seam detects automatically, probe assembly is along the axial enforcement scanning of checked container/pipeline, and by with realize driving probe assembly being connected of installation base plate along the circumferential scanning of checked container/pipeline.
Instrument in technical solutions of the utility model has very compact structure in the axial direction, can be by only slightly wide than probe scanning stroke scanning passage; Simultaneously, can directly be adsorbed on checked container/pipeline outer wall by the magnet-wheel assembly and implement to check, install easily; Can realize Fast Installation and location by aid by the circumferential guided way that lays in advance, and guarantee that instrument can not occur along the undesirable condition of checked container/pipeline axial play in motion process; Instrument can be realized by the installation base plate of changing different size (flexibility) the automatic detection of the container/Sizing In Butt Welded Pipes of different-diameter; In the situation that with checked container/pipeline matched well can be by only exceeding the approximately gap of 100mm than checked container/pipeline outer wall, realize the welding inspection that narrow space is radially pressed.
